Is the G5 the aluminium tower one?
Yep, it replaced a Plastic G4 tower - I thought all G5s were aluminium?
Also it occurs to me, when I get my 2017 iMac back from warranty repair, I could Ethernet the G5 and iMac together and then wipe the G5 hard drive via Disk Utility - so the G5’s original 160Gb hard drive could be included?
Just a thought
But I suppose it would help if I can find the original Install discs too
